SPECIFICATION forming part of Letters Patent No. 424,333, dated March 25, 1890..

Application filed August 17, 1889. Serial No. 321,063. (No model.)

To all whom i6 mfr/y concern:4

Be it known that I, WlLLLrn WATSON MC- ALPINE, a citizen of the United States, residing at l-lolieee, in the county of Greene and State of Alabama, have invented a new and useful Shelf", of which the following.,r is a specification.'

This invention has relation te shelves especially adapted for stores, and among the objects are to provide a series of shelves of the usual construction with means for preventin'g access thereto of dust, vermin, the.

XVith these general objects in view the invention consists, mainly, in mounting upper` and lower sashes in each section of shelving and weighting' the same so that they have a tendency to risc; and, l'urther, in suitable catches located at the basel of the section 'for engaging catches on the sashes, whereby they are' prevented from inilncnee by the weights.

and remain in a closed position, to automa-tieally rise when the catches are'disengaged.

Referring to the drawings, Figure 1 represents a perspective of a section of shelving constructed in accordfince with my invention. Fig'. 2 is a transverse section on the line .1: .fr of Fig. 1. lfig. l is a side elevation.

Like numerals el reference indicate like parts in all the lgures of thedrawings.

1 represents the sidewalls of a sectioin.

the base, and 3 the shelves mounted'in the side walls in the usual manner.

t represents the usual transverse molding or crown-piece, which, in this instance, in lieu of being set into recesses formed in the edges ot' the side walls landbeine'flush therewith, is simply secured thereto and projects therefrom. A jamb 5 is secured to each of the side walls directly under the molding at and al its inner face, 4thus forming a rear rcccss G. Openings 7 are formed in' the jamos 5 at their upper ends, and in said openings are mountedl weight pulleys 8, carrying weights 9 at their lower ends, said weights being located in the recesses 6. A bead 10 serves as the front wall .et the recess 6, and covering-strips 1'1 are fitted within the recess at the outside of the side walls, and are removable for the purpose of givingl access to thew ights.

llrepresents an upper sash vand i123 the lower sash, thelatterbeing next to the sheives. The lower rail of the upperouter sash 'and the upper rail of the lower inner sashV 14 and 15, respectively, are beveled in the -usual manner to overlap and forni tight connections with each other. Any number of lights 16 may be provided in each sash. The sashes are mounted in the jambs 5 and are divided hy a divisional bead 17, andto the upper endl of each of the sashes are connected their rcspective sashsoperating cords 18 and 15J-the former to the upper sash 1i and the latter to.

Athe lower sash 15and to the terminals of to have a constant tendency to raise both sashes.

The normall posit-ion of the sashes is as shown in Fig. 1-the upper sash raised bythe influence of the weight and the lower sash retained in its lowered position against the influence of its weightby the catch ot' said sash engaging the spring-latch.

To gain access tothe shelves protected by the upper sashes, saidv upper sash is drawn down until its catch 20 engages the companion catch' E21 on the base 2, when it is held trom an upi 'ard movement. By disegaging the catches the weights return thcupper sash to position. '10 gain access to th'e lower sash., the catchesV 2O and latch 21 thereof, which normally remain intel-locked, aredisconnecb.
